We won’t be covering the Diskmaker X option as it might be too easy for most OCD folks out there. Instead here’s some terminal action:
With the assumption you have the OS X Mavericks installer in your Applications folder and your USB Driver is formatted as OS X Extended (Journaled) with volume name “Untitled”. Type the following command into Terminal.

There are several keyboard combinations that can be used to take screenshots in OS X. The SystemUIServer process handles these commands.

Command-Shift-3: Take a screenshot of the screen, and save it as a file on the desktop
Command-Shift-4, then select an area: Take a screenshot of an area and save it as a file on the desktop
Command-Shift-4, then space, then click a window: Take a screenshot of a window and save it as a file on the desktop
Command-Control-Shift-3: Take a screenshot of the screen, and save it to the clipboard
Command-Control-Shift-4, then select an area: Take a screenshot of an area and save it to the clipboard
Command-Control-Shift-4, then space, then click a window: Take a screenshot of a window and save it to the clipboard
In Leopard and later, the following keys can be held down while selecting an area (via Command-Shift-4 or Command-Control-Shift-4):

Space, to lock the size of the selected region and instead move it when the mouse moves
Shift, to resize only one edge of the selected region
Option, to resize the selected region with its center as the anchor point

OS X’s TimeMachine software had native support for network backup until the OS X Leopard 10.5.2 was released. Apple had its own reasons for the decision to remove network backup, but many of us would like to be able to still back up over the network.

How do you do it?

Fortunately there is an option to turn-on network support for TimeMachine by running the following command in terminal:

We can finally see network hardrives in selection for backup places. The problem might seem solved, however this is just the beginning.

If you select a network drive for backup, you will see a very familiar message:

the backup disk image could not be created

TimeMachine only supports Mac OS Extended (Journaled) file system.

The solution is to create a place on the network, which will trick TimeMachine, into thinking that it holds data in Mac OS Extended (Journaled) file system. This trick is accomplished via copying a sparsebundle image (with special name) to a network share. You have to do following steps for to make TimeMachine successfully run a backup.

OVERVIEW

Enable network hardrive support in TimeMachineMount network shared place for backup data

Create a sparsebundle virtual image

Copy the sparsebundle virtual image to the network shared place

Set up TimeMachine for network backup

Optimisation and other information

1. Enable network hardrive support for the TimeMachine software

Network hardrive support for TimeMachine is turn off by default. For changing this fact we have to type following command to the terminal:defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1

After that, you should see mounted network harddrive in TimeMachine’s locations for backup. If it is not this case, probably a restart is needed.

2. Mount Network shared place for backup data

If you have a shared location for backup data on Linux server, you can map the directory as a drive to Mac in Finder application. You have to do following steps:

Click GO and then “connect to server” in finder menu.

Write following path if your sharing is based on protocol samba (SMB): SMB://<IP_ADDRESS_or_COMPUTER_NAME>/<NAME_of_SHARED_PLACE> (e.g. SMB://192.168.1.25/Backup)

3. Create a sparsebundle virtual image This step is very important, because the TimeMachine doesn’t allow to backup data to a network drive, which has any file system except “Mac OS Extended (Journaled)”. So we have to create a disk image in “Mac OS Extended (Journaled)” format.
We have two ways to do it:

Open disk utility (Disk Utility) and create new virtual disk with following atributes:

The previous step can be done by one command in terminal: hdiutil create -size 150g -fs HFS+J -volname “Backup of MacAlec” MacAlec_00ef9a048c4f.sparsebundle

3. Copy the sparsebundle virtual image to the network shared place
You can copy the sparsebundle image to the network shared place using one of the following steps:

Copy the file to shared place by drag and drop operation in Finder application.
If you prefer to work with the terminal, you can type this instead: cp -r <sparsebundle_image_disc_location>/<computer hostname>_<hex mac address of en0 interface>.sparsebundle /Volumes/<NAME_of_SHARED_PLACE>/(e.g. cp -r /Users/Alec/Documents/MacAlec_00ef9a048c4f.sparsebundle /Volumes/Backup/)

Now we can safely delete the sparsebundle image copy on local computer once we are sure that it has been copied to the shared location.

Set up the TimeMachine for network backup

Open TimeMachine preferences (in SystemPreferences).
Click on Change Disk button for select the network drive for backup. (We have to select the “Backup”in our case.)
The first backup will start in two minutes. TimeMachine supports incremental backup, thus the first backup can take very long time (it is depends on network bandwidth and amount of backup data).

If you want to eject the mapped shared volume (/Volumes/Backup in our case), you have to do it within the two minutes countdown before backup starts or after backup is finished. TimeMachine has its own mechanism for mapping network hardrives, so a backup process isn’t interrupted by your hard drive mounting or unmounting. TimeMachine will automatically mount the virtual sparsebundle image, when the backup starts. You will see Backup of <computer_name> as connected device on your desktop, so you won’t need to manually mount the network hard drive later.

4. Optimisation and other information
in order to avoid long delays in backup process caused by Spotlight indexing, You should set the Spotlight application to not index the mapped network drive. Here’s how to remove spotlight indexing for a hard drive:

Open up the Spotlight software preferences in system preferences window
Move to privacy options and add the network drive by plus symbol
If you’d like to back up a little less often, you can modify the file

com.apple.backupd-auto.plist which is located in /System/Library/LaunhDaemons/ to change backup time interval. Open up the file in text editor and find the section: <key>StartInterval</key> <integer>3600</integer> You should change the number 3600 to the number of seconds of your backup interval.
